FireChat

FireChat is a messaging application that allows users to communicate even without an internet connection or a mobile network. It uses mesh networking technology, which enables devices to connect directly to each other via Bluetooth and Wi-Fi. This means that users can send messages to others nearby, and the app relays messages through nearby devices, effectively creating a decentralized communication network. FireChat gained attention during events where traditional communication networks were overwhelmed or unavailable, such as protests or natural disasters.
